Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishNeutron diffraction data for pure supercritical water and supercritical mixtures of water and CO2 are analyzed by using the empirical potential structure refinement Monte Carlo simulation, and molecular configurations compatible with the experimental data are recorded. The analysis of the distribution functions of water cluster size in these fluids allows the identification of a percolation line, which separates gas-like states from liquid-like ones, in pure supercritical water. Solvation of CO2 in supercritical water inhibits cluster percolation, although the radial distribution functions show liquid-like behavior: this is likely to be due to the excess volume being localized around the CO2 molecules.

| Abstract: | Neutron diffraction data for pure supercritical water and supercritical mixtures of water and CO2 are analyzed by using the empirical potential structure refinement Monte Carlo simulation, and molecular configurations compatible with the experimental data are recorded. The analysis of the distribution functions of water cluster size in these fluids allows the identification of a percolation line, which separates gas-like states from liquid-like ones, in pure supercritical water. Solvation of CO2 in supercritical water inhibits cluster percolation, although the radial distribution functions show liquid-like behavior: this is likely to be due to the excess volume being localized around the CO2 molecules. | |
